Problem – Companies and supply chains, such as those in the grocery industry, continuously face stricter requirements in the form of customer satisfaction, quality, profit margins, as well as information sharing in order to stay competitive. One specific technology that may be used in dealing with increasing competitive demands is the radio frequency identification (RFID) technology. A wide body of research recognizes the positive impacts from RFID, yet even so, doubts and uncertainty have been present among different supply chain members in industries striving to put the RFID technology to use. Nevertheless, many actors in the Norwegian grocery industry are replacing traditional wood pallets with plastic pallets, and these pallets are integrated with RFID tags. Purpose – The purpose of this thesis is to investigate how plastic pallets with integrated RFID tags can contribute to improve supply chain efficiency in the grocery industry. Also, the managerial perception on the pallets and their accompanying technology will be compared to the existing literature, to identify if the managerial opinion supports the literature, and if not, where the gaps exist. Method – The thesis combines an exploratory and an explanatory qualitative study of the managerial perception of RFID pallets in the Norwegian grocery industry, and investigates whether the perception supports the literature. The empirical material is gathered through telephone interviews with logistics and warehouse managers in the various companies. Conclusions – Physical implications: The managerial perceptions’ support towards the addressed implications of the reviewed literature is mixed. RFID pallets improve automatic operation processes through reduction in downtime and eases physical handling of pallets. Additionally, sorting of pallets becomes less labor demanding. Regarding holding of goods, the managerial perceptions do not seem to view RFID pallets as an important factor for efficiency improvement. Information related/RFID aspects’ implications: The managerial perceptions in these concerns were based on plans and thoughts, since the technology had not been put to use. There is a difference in producers’ and wholesalers’ perception of whether efficiency in receiving of goods can be improved through utilizing RFID pallets. Concerning dispatching of shipments, the managerial perceptions support the literature in that information-related activities can be automated, and thus improve efficiency and reduce risk of human errors. In regards to information sharing, the managerial perception supports the literature, but highlights that the information’s nature determines whether sharing is considered. Further research could include the retail store level to get a more complete supply chain picture, and also apply the research methods to a larger area in order to investigate the transferability to other industries and countries.

Global industrialization was developed in response to both consumers and manufacturers demand for lower product prices and availability of goods and services. As a result, products are transported greater distances. Shipping constitutes the majority of costs in the export/import supply chain. Shippers and buyers commonly attempt to offset these costs by maximizing the capacity of ocean freight containers (cube or weight). Boxes (usually constructed of corrugated fiberboard) containing consumer grade products are commonly floor loaded into containers to maximize capacity. Boxes that are not floor loaded are likely to be unitized on pallets in containers. Beyond maximizing a container with cargo, a defined decision to determine which method of loading is most efficient in regard to cost and time does not exist. For this research, field studies were conducted and questionnaires were distributed to identify the variables that influence efficiency. A method to make an efficient decision was developed by incorporating the variables into a model. The model compares the overall export/import supply chain efficiency for boxes that are floor loaded to boxes that are unitized on pallets in containers. The recommended decision is determined by comparing the shipping and handling costs and the receiving dock door capability for the two loading methods. The results of this research reveal that floor loading boxes can provide a higher value per container due to increased capacity. Increased capacity by floor loading often reduces the number of containers needed to meet daily demand. However, since manual labor is utilized for the loading/unloading process, more time is required, which results in higher labor costs and restricted product throughput. Unitized boxes loaded in containers on pallets can limit container capacity, but allows for faster loading/unloading times (if no incompatibilities between product and pallet or pallet and/or material handling equipment exist), reduced labor costs, and the potential for increased product throughput. Importing boxes unitized on pallets commonly requires more containers to meet demand, but fewer receiving dock doors. Utilizing fewer dock doors allows otherwise occupied doors to be available to receive additional product. The decision to floor load or unitize exports/imports needs to be made on a SKU basis meeting daily demand, not only per container capacity. Labor cost, pallet cost, the magnitude of box variation between loading methods, and the ability of the receiver to process containers are all influencing factors in determining which loading method is most overall efficient. Given the current cost for containerized shipments and considering all costs, most consumer goods are more efficiently shipped floor loaded. When additional containers would be needed to meet demand for product unitized on pallets, floor loading will be more efficient. When there is only a small difference in box count between floor loading and palletizing, palletizing product will be more efficient. This will often occur when loads will meet container weight capacity before it reaches volume capacity. If the product is too heavy to move manually it will be palletized. / Ph. D.

Although theory suggests the importance of the influence of selected human factors as antecedents to the efficiency of upstream supply chains, research findings of the actual influence human factors may have are lacking in evidence. This study examines its influence on the basis of a literature study as well as an empirical study in an attempt to find hard facts to its role in supply chain efficiency. Six different human factors were identified, based on opinions from key opinion leaders in this field of study and investigated its relevance by means of empirical research. Results suggest that the selected human factors that play a definite role in upstream supply chain efficiency are: individual’s principles, individual’s goals and company’s goals for the individual - common goals, personality, ability/trainability, general skills and training, and mutual trust and understanding. Findings presented interesting results that should influence the way management handles its human assets in the organisational environment. / Thesis (MBA)--North-West University, Potchefstroom Campus, 2013.

The aim of the study was to explore the fundamental operational risks, mitigation strategies and the key performance indicators (KPIs) in last-mile delivery (LMD) of perishable goods for African and Asian retailers. Particularly, the research was guided by the following research questions.  RQ1: What operational risks are related to LMD of perishable goods for African and Asian retailers? RQ2: How do African and Asian retailers mitigate these operational risks?  RQ3: What KPIs can be used to ensure the efficiency of LMD of perishable goods?

Background & aims: Prior research has, due to the ongoing Covid-19 pandemic and the resulting supply chain (SC) disruptions, increased the level of investigations in the field of SC resilience strategies. Even though many studies have been conducted within the field, little is known about the effectiveness and efficiency of those strategies. As food SC’s (FSC’s) are among the most important SC’s in our societies, their conservation is of great importance. As the operational purchasing process within the FSC was one of the areas within the SC that was strongly affected by the pandemic, this process will be the focus of the paper. This study seeks to identify the most applied SC resilience strategies for operational purchasing activities in FSC’s for various SC disruptions from a SME food retailers perspective. Furthermore, a framework of how to measure the effectiveness and efficiency of those strategies will be developed. Method: To collect relevant empirical data to answer the purpose of the study a qualitative multiple-interview study is conducted based on semi-structured interviews with respondents of the three different case companies. The case companies were selected and four interviews with one to two respondents per company were conducted. European SME food retailers of long shelf life goods are used as case companies to investigate the research gaps. Results: The study found out that the application of theory revealed the five most applied SC resilience strategies (SC flexibility, inventory management, end-to-end (E2E) SC visibility (SCV), information technology (IT) tools and SC cooperation) in operational purchasing, differences between SME food retailers according to their company size and maturity level. The KPIs identified to measure the effectiveness and efficiency of these SC resilience strategies were found to be applied. The KPIs provided are the basis for measurement opportunities that should be adapted and expanded depending on the business model and complexity of the company as part of the SC design. Contributions: The study adds value through theoretical and practical contributions of the most applied SC resilience strategies within operational purchasing from a SME food retailer perspective and their performance measurement system for measuring efficiency and effectiveness. Limitation & future research: The study is limited to the Covid-19 pandemic as a major reason for the triggering of the investigated SC disruptions. Further limitations can be seen within the selection of the case companies. Future research should investigate the differences between SME within their application of SC resilience strategies for their operational purchasing activities, just like the differences between strategic and operational purchasing. Key words: supply chain resilience strategy, supply chain disruption, Covid-19 pandemic, supply chain effectiveness, supply chain efficiency, performance measurements, key performance indicator, food supply chain, food retailers, purchasing process, operational purchasing

Large product assortments commonly lead to that fast fashion retailers have a large number of transport cartons, with varying sizes, to distribute products from manufacturing sites to distribution centers. Ultimately, the transport cartons have a large impact on the supply chain efficiency, as they affect several nodes in the supply chain network. Previous research has considered transport cartons’ impact on individual supply chain nodes, but little research has been devoted to evaluate the transport cartons impact on the supply chain network as a whole. Thus, this thesis aims to contribute with knowledge to bridge the gap in literature by investigating how a company’s transport cartons affect the overall supply chain efficiency, by applying a holistic perspective. The thesis was conducted as a case study in collaboration with Hennes & Mauritz (H&M), aworld-leading fast fashion retailer. The research identifies opportunities and challenges related totransport carton usage, and how the cartons impact supply chain efficiency. Moreover, the research evaluates the costs associated with different sets of transport carton sizes, based on acost estimation model constructed on data provided by H&M. It is concluded that a small set oftransport carton sizes could increase supply chain efficiency and generate potential cost savingsdue to mainly two reasons. First, a small set of transport cartons could lead to efficient containerloading. Second, it could lead to efficient carton handling and optimal space utilization in thedistribution centers. / Till följd av stora produktsortiment har snabbmodeaktörer ofta ett stort set av transportkartonger, med varierande storlekar, för att distribuera produkterna från tillverkning till varuhus. Eftersom transportkartongerna påverkar fler noder i försörjningskedjan, har de följaktligen stor påverkan på hur effektiv försörjningskedjan är. Tidigare forskning har utvärderat hur transportkartongerna kan påverka enskilda noder i försörjningskedjan, men lite fokus har ägnats åt att utvärdera kartongernas effekt på försörjningskedjan, sett ur ett helhetsperspektiv. Detta examensarbete syftar till att bidra med kunskap för att överbrygga detta gap genom att undersöka hur ett företags transportkartonger påverkar den totala försörjningskedjans effektivitet genom att tillämpa ett helhetsperspektiv. Examensarbetet genomfördes som en fallstudie i samarbete med Hennes & Mauritz (H&M), som är en av de världsledande aktörerna inom snabbmode. Studien identifierar möjligheter och utmaningar relaterade till transportkartonganvändning, och hur kartongerna påverkar försörjningskedjans effektivitet. Vidare utvärderades kostnaden av att ha olika uppsättningar av transportkartonger, baserat på en beräkningsmodell grundad på data från H&M. Resultaten visade att ett litet set av transportkartonger kan ha positiv påverkan på försörjningskedjans effektivitet och generera kostnadsbesparingar till följd av två huvudsakliga anledningar. Den första anledningen är att ett litet set förenklar effektiv containerladdning. Den andra anledningen är att det kan leda till mer effektiv kartonghantering på lager och bättre utnyttjande av lagerutrymme.

This thesis explores the integration of IoT protocols to enhance supply chain efficiency and sustainability by developing a flexible automated system. The research covers the integration of a palletization optimizer with a flexible robotic platform, a project conducted in collaboration with OpiFlex and Linköping University. Flexibility and sustainability in production, particularly in the food and beverage industry, are critical yet challenging to achieve. This research addresses these challenges by proposing a system that aligns the output with customer needs by combining these technologies. The research employs a combination of case study and exploratory methodologies. The development approach synthesizes elements from Set-Based Design, Point-Based Design, and Agile development frameworks. The primary research questions focus on identifying the best system architecture for integrating the palletization optimizer with a lower-level automation platform and outlining the steps needed to transform this integration into a commercially viable product. The system includes the optimizer, capable of processing customer orders and configuring products on mixed output pallets, integrated with a flexible robotic system provided by OpiFlex. The work involved evaluating communication protocols, MQTT, OPC UA, and TCP/IP, and designing robust interactions and interfaces between the subsystems. The results demonstrate the system's architecture and interaction protocols.  The thesis concludes with a discussion of the results in comparison to the application scenario and the standards consulted. The conclusion is that the chosen interface practices should remain largely intact but be re-developed using an OPC UA-based architecture. The main reasons for this are its support for both pub/sub and client-server models, increased security, and greater support for enterprise application integration. However, depending on the specific application, the downsides of OPC UA may outweigh its benefits.
